Thanks for the response. Seems like a good way to go for me. Anyone have a S3 on Sprint and tested out LTE speeds? Sprint's 3G speeds are so horrible so I am kind of curious how their LTE is doing. They would be my other option besides T-Mobile.
I'm on Sprint, but LTE has not launched yet in Los Angeles. What city do you live in?
Here's a link to a forum of cell network nerds tracking Sprint's LTE rollout, I'm sure you'll be able to find a thread that pertains to your area with speed test results:
